New York-based jewelry line Giles & Brother was founded in 2001 by siblings Philip and Courtney “Giles” Crangi. Creating pieces that channel America’s pioneering spirit, the duo often detail their sterling silver and brass designs with an oxidized finish for a rustic look. The coveted styles include bracelets, necklaces, and the label’s signature Railroad Spike cuffs, which launched in 2005 and were inspired by the famed golden spike used to ceremonially join the First Transcontinental Railroad.
